Crystal Structure and Physical Properties of High Pressure Hydrides

The technique for compressing gaseous hydrogen to pressures of up to 9 GPa at temperatures to 500 °C (and recently1 to 1000 °C) developed at ISSP RAS made it possible to synthesize bulk homogeneous hydrides of a number of Group VI-VIII transition metals which cannot be hydrogenated by standard procedures2. This enabled us to prepare hydrides of all 3d- and 4d-metals (except ruthenium) and of many their alloys, and to systematically study their crystal structure and physical properties as function of the position of the initial metals in the Periodic Table (Fig. 1). Most of the hydrides are nonstoichiometric interstitial phases (solid hydrogen solutions) with wide homogeneity ranges of composition, that allowed the investigation of their properties as function of the hydrogen concentration as well.
